MALCOLM ROBERTS is a former Australian mining consultant who thinks the United Nations is using the “scam” of human-caused climate change as a cover story while it builds an all-powerful world government.

At every opportunity, Roberts, a former coalface miner, has claimed there is “no empirical evidence” to show that carbon dioxide from burning the coal that he used to dig up affects the climate.

As climate science denial goes, Roberts’ position is as far to the fringe as you can go, mixing conspiracy theories with outright rejection of the conclusions of science academies and institutions across the world that humans are causing climate change.

Much time, too, was given by the media to an odd letter sent by Roberts to former Australian prime minister Julia Gillard. The letter was written in the distinct style of a “sovereign citizen” – the radical movement of anti-government extremists.

Roberts has denied being a “sovereign man” and dismissed the letter as a mistake. He has strongly denied any promotion of anti-Semitic conspiracies.

But in any case, Roberts’ arrival on the national scene has been irresistible in a media environment driven by clickbait and conflict.

Roberts has spent the last seven or eight years working as the project manager of the Galileo Movement — a climate science denial group launched in 2011.

But over that period, as well as developing his talking points and writing verbose reports, he has been writing complaint letters and emails to journalists, politicians and the institutions where climate scientists work.

His unrelenting harassment of climate scientists and academics working on climate change over several years (he would call it doing due diligence) is worth documenting because it points to the kind of activities Roberts might get up to now that he has been elected.

Roberts has written letter after letter — email after email — to the bosses of some of Australia’s best known scientists, often copying in long lists of politicians, fellow denialists and journalists. Roberts has posted all his correspondence on his website.

Roberts also tried to engage then education secretary Christopher Pyne, who is now defence minister, with a letter demanding his department investigate Cook and Hoegh-Guldberg.

In a response to Roberts’ complaint about Hoegh-Guldberg and Cook, the university’s then acting VC Professor Max Lu wrote:

UQ has also thoroughly investigated your claims of misconduct, lack of integrity, conflicts of interest and other matters in relation to Mr Cook and Professor Hoegh-Guldberg, and have found them to be baseless.

Engineering complaint

In arguably Roberts’ greatest display of overreach, in October last year, he filed a formal complaint to the Board of Professional Engineers of Queensland — a government agency charged with regulating the engineering industry in the state.

Roberts targeted three people who had given expert evidence in a court case opposing the development of the giant Adani Carmichael coal mine in Queensland.

Roberts attempted to argue that because the experts had commented on how carbon dioxide causes global warming, this constituted engineering advice the trio were not qualified to give, and so contravened the state’s Professional Engineers Act. (Essentially, Roberts was reclassifying the world's climate scientists as engineers in order to complain about them).

finding and action will significantly contribute to safeguarding the engineering profession relying on empirical evidence and the integrity of all professions at large for the protection and benefit of our state and all Queenslanders.

How did Roberts’ complaint fly? DeSmog understands that after consulting the scientists, the board decided to take no action.

In January 2011, Roberts sent a rambling 5200-word email to University of Melbourne climate scientist Dr David Karoly, 'Copied to University of Melbourne Chancellor and Vice-Chancellor', accusing Karoly of spreading “falsities”.

'If you have already made up your mind that the climate scientists, physicists, oceanographers, most geologists, biologists, hydrologists have just made this all up, then I do not think I can help.'

In February 2013, Roberts sent one of his reports to a list of academics at universities across Australia, as well as directors at the Bureau of Meteorology and science agency CSIRO.

Roberts demanded that unless; 'by March 1st' they provided a list of 'specific and scientifically or factually justifiable' reasons why they disagreed with his findings, that he would presume they agreed with it.

In a “lawful notice” (above), Roberts also demanded scientists and others should then withdraw all of their past claims linking carbon dioxide to climate change.

He made similar demands to journalists, who also received “lawful notices”.

Roberts has also demanded that several MPs “resign immediately” unless they could prove to him that human-caused climate change was real.

“Campaign of intimidation”

One of the academics on the receiving end of Roberts complaints, John Cook, of the University of Queensland, told DeSmog:

Beneath the public attacks on climate science, scientists are also subject to a more insidious campaign of intimidation, otherwise known as the subterranean war on science. This takes the form of complaints to universities to get scientists fired, complaints to journals to get papers retracted and FOIrequests to pick through scientists’ emails.

Malcolm Roberts was prolific in emailing complaints to The University of Queensland about my research and our course on climate science denial. As a researcher studying denialist attacks on science, I used the experience as a teachable moment - recording a video about the nature of attacks on science as well as interviewing the world's leading scientists who described their own experiences of harassment which were eerily similar to my own experiences.

It's crucially important that we shine daylight on this kind of behaviour. The public, universities and academic journals need to understand the techniques denialists employ to impinge on scientists' academic freedom, in order to reduce their damaging impact on science.
